If you smell gas, evacuate immediately – even a small leak can cause explosions. Do not use any electrical devices including phones – they can create sparks that ignite the gas. Check for pilot lights that are yellow or orange instead of blue. Plants near gas lines can wither and discolor for no apparent reason. A consistent, higher-than-normal gas bill could also indicate a leak.
If you have a gas leak in your home, you might notice a variety of symptoms, including a rotten egg or sulfur smell, a hissing sound, or the appearance of bubbles on surfaces around leaking pipes and appliances. You might also notice dead houseplants or a higher gas bill than usual without any explanation. If the leaking gas is near your water lines, you might see bubbles in standing water or wet areas in your yard.
A rotten egg or sulfur smell is the most common indicator of a gas leak. Natural gas is odorless, so it’s mixed with a chemical called mercaptan before entering homes to give homeowners the unpleasant odor to detect if there is a leak. This is a safety measure to protect you and your family from the potential for explosions when the gas comes in contact with air.
Another sign of a leak is hearing a hissing or whistling noise. The volume of the hissing will depend on how big the leak is, with larger leaks producing a louder sound. You may also hear a faint whistle when the gas is being released through loose connections. Listen carefully and remember the area where you heard the noise. This will help your plumber find and repair the leak more quickly.
In some cases, you might experience a dry or sore throat when you’re exposed to a gas leak. This is because the escaping gas can irritate your throat and other airways. The symptoms usually resolve once the leak is fixed and the gas is no longer escaping.
Other symptoms include feeling dizzy or lightheaded. These symptoms are caused by the displaced oxygen from the leaking gas, which makes it harder to breathe. This is similar to the way you might feel when suffering from a cold or the flu. It’s important to evacuate your home as soon as you notice a possible gas leak, and to have a certified inspector visit your house to assess the situation.
For a mild leak, you can open the windows, turn off pilot lights, and call your utility company to have them come out and shut off your gas meter if needed. For serious leaks, make sure you and your family are a safe distance away from the home and call 911 right away.
Signs
Natural gas is a great energy source that provides warmth, cooking and cleaning, but it is also dangerous if there is a leak. Whether the cause is shifting soil, corrosion underground or an accident such as digging into a pipeline, a gas leak can be a serious health risk and should be dealt with immediately. If you suspect that there is a problem with your gas line or appliances, call an experienced HVAC contractor to inspect the system and determine if there is a gas leak.
One of the most common signs that there is a gas leak is a hissing sound. This noise is a result of gas escaping from the leak and can be heard from a distance. It can also be accompanied by a whistling sound. Hissing sounds are usually heard near gas appliances, pipes or meters. If you hear these sounds, you should evacuate the area and call a technician immediately.
Another classic sign of a gas leak is the distinctive odor. Natural gas has a distinct, earthy odor that can be identified by most people. However, sometimes physical and chemical processes can cause the odor to fade or become undetectable. This is known as odor fade and is a reason why it is important to be aware of the other warning signs of a leak.
Other common signs of a leak include bubbles in wet areas, dirt getting kicked up in the air or white clouds and dust around gas lines. These indicate that the ground is absorbing the gas and creating an excess of pressure. Another telltale sign is a higher-than-normal gas bill. When a line leaks, it requires pushing more gas to your home to keep the heating and appliances working, which causes the increased bill.
Other symptoms of a gas leak include red or watery eyes, a lack of appetite, confusion, dizziness and other physical problems. If you experience any of these symptoms, evacuate the area immediately and call a technician to check the gas line for a leak. It is a good idea to have your gas lines checked periodically for safety and efficiency.
Treatment
A gas leak is a dangerous issue that can cause a variety of symptoms in both people and animals. Some of these symptoms include difficulty breathing, headaches, and nausea. In some cases, the symptoms can be quite severe and even lead to death if not treated in time. In order to prevent this, it is important to make sure that you have regular maintenance done on your pipes and to check for leaks often.
In addition, make sure that you store all of your chemicals and paints in a safe area away from your gas lines and appliances. Many of these substances can also leak and can damage the pipes. It is also a good idea to go through these supplies on a regular basis and throw out any that are no longer needed.
If you do suspect a gas leak, evacuate the premises immediately. Make sure that everyone goes to a safe place outside and does not return until the professional that comes out to assess the property has given you the all-clear. While evacuating, be careful not to use any electrical devices including cell phones as these can spark and ignite the gas.
Once outside, it is a good idea to leave all of the windows open as this can help to improve airflow and oxygen circulation. In some cases, this can help to reduce the severity of the gas leak and can make it less hazardous. It is a good idea to make sure that children and elderly people are evacuated as well, along with any pets that you have.
A professional will be able to tell you if your situation is a grade 1 or a grade 2 leak. Grade 1 leaks are considered to be extremely hazardous as they can be explosive and require immediate response and repair. Grade 2 leaks are less hazardous but can still be damaging. These leaks are typically buried in the ground and may be affected by freezing or adverse soil conditions. Lastly, grade 3 leaks are not considered to be as hazardous but can still be harmful. These leaks are usually caused by aging or corrosion of the pipe and are not as severe as either grade 1 or 2.
Prevention
There are many steps you can take to prevent gas leaks and minimize the risk of explosions. First, it’s important to recognize the signs of a leak. If you smell rotten eggs, hear creaking sounds, or see an unusual increase in your gas bill, evacuate your home immediately and contact emergency services. It’s also important to schedule annual inspections of your gas pipelines and equipment. Lastly, be sure to install carbon monoxide detectors and keep all appliances properly maintained.
Once you’re at a safe distance, call your gas provider’s emergency number and provide them with accurate information about the location and intensity of the odor. Avoid using any electrical switches, devices or anything that creates a spark, as these may ignite the gas and cause an explosion.
It’s also a good idea to check on the safety of any nearby trees or plants. If they begin to wither or die, it’s likely due to a gas leak in the surrounding area.
When you notice any of the symptoms of a gas leak, evacuate your home and leave doors open as you exit to allow the gas to dissipate. Be sure to inform your neighbors of the leak and urge them to take precautions as well. Do not attempt to investigate or fix the leak yourself, as this can be extremely dangerous.
Remember, explosions from gas leaks are typically caused by a combination of leaking gas and a spark. This can be anything from a lit candle or cigarette to an electrical switch or doorbell, as even small sparks have the potential to ignite gas.
If you’re not able to evacuate, turn off the gas pilot light and open windows. Then, call your local gas utility company from a safe location to have an inspector arrive and shut off the gas valves for you. They’ll also be able to inspect your property and ensure that there isn’t a deeper problem with the pipeline or equipment. Leaving these things unattended can lead to serious complications, including an explosion that could destroy your entire house and possibly injure or kill you and your loved ones.
